SPECIFICATION forming part of Letters Patent No. 783,759, dated February 28, 1905.

Application fi led November 22, 1904. Serial No. 233,841.

To (all. whom. 7 'ntugl (Bo/worm Be it known that I, GEORGE J. R'EooRn, a citizen of the United States, residing at Conneaut, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Fastenings for Curtains and Rolls and other Articles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to provide a simple, cheap, el'licient, easily-applied, and easily-removed device for fastening the edge or a curtain or other fabric to a roller or other article, part, or structure. To this end I form in the roller or other part or article a dovetail groove and combine therewith a resilient :fastoning of undulating, zigzag, or other laterally-projecting form adapted to be worked into the said groove within the folded edge of the curtain, so as to spring sidewise within the broader part of the said groove and behind the walls of the narrow neck thereof, catching behind the material of the said roller on each side of the neck of the said groove and holding the curtain securely. The latter may, however, easily be freed at will by partly turning the said rod and Working it outward with a weaving motion, so as to successively extricate its undulations or laterallyprojecting parts from the groove.

In the accompanying drawings, Figure 1 represents a perspective view of a curtain, partly sectioned and broken a\vav,"its roller, and means for-fastening the same together embodying my invention. Fig. 2 represents a cross-section on the line 2 2 of Fig. 1; Fig. 3, a longitudinal section on the line 3 3 of lliig. 2.; Fig. t, a front elevation of the upper part of Fig. 1 broken away, showing the fastening-rod modified in short sections; Fig. 5, a detail viewof a part of the fastening-rod broken ofli, and Fig. 6 a detail view of one of the short rods or sections of the fastening-rod shown in Fig. 4:.

A designates a hollow metal roller having a longitudinal dovetailed metal groove (.0 formed therein to receive the folded edge 7) of a curtain B. Such grooves thus used are already common, various kinds of fastening devices which enter the fold of the curtain edge and the groove being employed therewith to hold the curtain therein. The said groove may of course be formed in a wooden roller or any solid article, part, or structure and the form of said groove in cross-section maybe varied indefinitely, provided it has a narrow neck and a wider inner part. Also any other fabric or material capable of being folded to enter said groove and receive said fastening-rod may be thus attached instead of a curtain.

designates the fastening-rml, which, in combination with the grooved roller or other grooved part, constitutes the salient novelty of the case. This 'rod is preferably of small spring-wire bent laterally each way, as shown in the drawings, into alternating undulations, necessarily arranged at intervals on each side and normally giving the fastening rod a greater Width from the line of outermost points of the projecting undulations on one side to the like line on the other side than the neck of groove uv oreven than the wider part ofsaid groove. The size and cross-section of the red are, however, variable at will withoutdeparting from my invention, and the angles or curves of the undulations may be also changed, giving them more or less of a zigzag character. As shown, they are regular; but some of them may he obviously extended laterally more than the rest or given other irregularitiesof position or form either in the same plane or other planes. bionic of these are illustrated in the various detail figures of the drawings, as above stated. It is not necessary that the rod should be resilient throughout its length, although this is preferable, for resiliency in the laterally-projecting parts of it willsul'lico. Also it need not be in one piece, though usually and with most advantage made so, but may be in several sections or iinlependent parts l, as illustrated in Fig. a. Each of these short rods or sections is provided at its ends with hooks adapted to extend out at least as far as the neck of the groove, when the said section is inserted therein for convrmience of grasping and removal. When the continuous rod is employed, italso maybe provided with these books, as shown, but should, in any event be of greater length than the said groove to l bending may be done with great rapidity by present a protrudingend suliiciently long for I though of course at a lower rate of speed, It

assistance in removal. Steel will be usually employed as a material; but other resilient metal or non-metallic material may be substituted. The method of applying this fastening-rod is to press the first undulation of-itat one end into the groove, passing it down through the narrow neck thereof, then turnl tile fabric.

ing the said undulation to one side in the broader part of the groove under thematerial of the roll projecting on that side to the neck of said groove, while the next undulation or 1 stitute (see, g., my Patent No. 768,693, dated laterally-extending part of the rod is similarly introduced and turned in the opposite direction under the material on that side of the neck of the groove, this procedure being continued from end to end of the rod in a weaving motion; alternating from side to side until the entire rod is embedded, with the folded edge of the fabric in the inner and broader part of the groove. It will then withstand a considerable direct strain, inasmuch as the undulating parts of the rod, which were necessarily compressed in their introduction into the groove and subsequently expanded laterally behind the material of the roller on each side of the neck of said grloove, will hold the folded fabric spread against the wall of the broader part of said groove behind said neck, and the pull on the curtain only serves to wedge it there, especially since a strain on either side of the rod tends to force the undulations on the other side farther under the proximate part of the roller, and any pull must thus act on both sides and all undulations of the rod. hen it is desired to detach the curtain from the roller, the fastening rod is removed by reversing the above-described weaving motion, beginning, as before, at the protruding end. If several short rods or sections of rod be used instead of one long one, the same operation of insertion or re moval is repeated in detail, though if each section contains but a single undulation it will of course be moved or turned sidewise in one direction only, the next section being moved or turned in the opposite direction, and so on until all are inserted.

In denominating the fastening device a rod I use merely a convenient general term, not restricting myself to any particular limit of size nor excluding sizes and forms which might possibly be outside of some popular uses of the word. I include any fine-wire filament or shred having the necessary resiliency and tenacity to be used, as hereinbefore described, as well as any analogous article or element of greater cross-section or mass havingthese necessary attributes.

The fastening-rod in its preferred form herein illustrated and described is exceeding cheap and easy of manufacture, being no more than a piece of straight spring-wire bent into alternating undulations.

In illustrating a roller I have omitted the interior spring mechanism as having nothing to do with the present invention, also and for the same reason all exterior devices actuated thereby, except a part of the curtain.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A fastening-rod having resilient portions which extend laterally outward at intervals, in combination with a part having a groove which is narrower in front than at the rear and adapted to receive a fold of flexible material, as well as said rod which is inclosed by said fold, the said rod being adapted to expand laterally in said groove after insertion and turning, thereby spreading the said flexible material behind those portions of the said grooved part which are at the sides of the neck of the said groove substantially as and for the purpose set forth.

2. A resilient fastening-rod having laterall y-extending integral undulations, in combination with a part having a groove which is narrower in front than at the rear and adapted to receive a fold of flexible material, as well as said rod which is inclosed by the said fold, the said rod being adapted to expand laterally in said groove after insertion and turning, thereby spreading the said flexible material behind those portions of the said grooved part which are at the sides of the neck of the said groovesubstantially as set forth.

3. A resilient fastening-rod provided with lateral undulations, in combination with a dovetail grooved roller adapted to receive the said rod and a fold of curtain inclosing the same, the said rod being woven into said groove by alternating lateral movement and turning, to lock said curtain to said roller substantially as set forth.

l. A resilient fastening-rod provided with a terminal hook or handle and portions extending laterally on both sides, in combination with a part having a groove which is narrower in front than at the rear and adapted to receive a fold of fabric and to permit the said The cutting and l rod to be woven obliquely into the broad rear 10 said fold and look the latter therein by its expansion and engagement for the purpose set forth.

in testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
